Thanks everyone! The coin vise holds some 61 different coins. There wasn't enough room to write all of them on the holder. !
It is made with US denominations in mind, but it will accommodate a wide variety of coins from many countries. The full list can be found at: http://airgraver.com/Multi-Coin-Vise.htm In addition, the lower recess of the Native American pocket is one inch so that one inch discs can be held.

if i'm not wrong around 100 coins, i haven't test all my foreign coins but i'm sure that definitly is a universal fixture and the new version have a bigger size too that the mine don't have and will hold more
